Introduction:
In web design , font selection is an important aspect. A suitable font can enhance the readability and aesthetics of a web page. In CSS, we can control font style and size through the font-family and font-size properties. However, using these two properties correctly is a challenging task. This article will show you how to choose the correct font style and font size, and provide some specific code examples.
1. Font-family font style selection guide:
- Use universal font family:
When choosing a font style, you should give priority to using universal font families. Font family. Such as "serif", "sans-serif", "monospace", etc. These font families define the overall style of a type of font and can display consistent effects on different operating systems and devices. Here are some common generic font families:
body {
font-family: serif;
}
h1 {
font-family: sans-serif;
}
code {
font-family: monospace;
}- Specify a specific font name:
If you need to use a specific font style, you can do so by specifying the name of the font . Try to choose fonts that are installed by default on the system. If the font is not present on the user's system, the browser will use a fallback font instead. Here is an example of specifying a font name:
h1 {
font-family: Arial, Helvetica, sans-serif;
}- Using a custom font:
If you wish to use a custom font in your web page, you can pass @ font-face rules to load font files. Place the font file on the server and reference it using a relative or absolute path. The following is an example of loading a custom font:
@font-face {
font-family: "MyFont";
src: url("myfont.ttf");
}
h1 {
font-family: "MyFont", sans-serif;
}2. Font-size Font size selection guide:
- Use relative units:
In It's a good practice to use relative units when setting font sizes. Relative units automatically adjust font sizes based on the user's device and preferences. Here are some common relative units:
em: Relative to the font size of the parent elementrem: Relative to the root element (usually the<html>element) font size%: Percentage relative to the parent element
body {
font-size: 1em;
}
h1 {
font-size: 2em;
}
p {
font-size: 120%;
}- Use absolute units:
In some cases you may want to use a fixed font size. In this case, you can use absolute units such as px, pt or rem. Here is an example using absolute units:
h1 {
font-size: 24px;
}
p {
font-size: 16pt;
}- Responsive font size:
To achieve optimal font size on different screen sizes and devices, you can Use media queries and property interpolation with CSS. For example, font sizes can be automatically adjusted based on screen width. Here is an example of responsive font size:
h1 {
font-size: 24px;
}
@media screen and (max-width: 768px) {
h1 {
font-size: 18px;
}
}
@media screen and (max-width: 480px) {
h1 {
font-size: 16px;
}
}Conclusion:
Properly choosing font style and font size is an important task in web design. By using appropriate font styles and relative units, you can ensure the readability and aesthetics of your web pages. At the same time, by specifying font names and loading custom fonts, you can achieve more personalized and unique design effects.
